Respuesta :
I am very stuck between A and B on this, they are both similar. I know South Vietnam fell days after the U.S. pulled out of the war(1973). The two countries did not become one communist country until two years later after the U.S. pulled out of the war though (1975). So I am going to say the answer is A.) the communists had taken over South Vietnam, But Eisenhower's domino theory did not occur.
Let me know if I was correct or not. If I was correct and/or helped at all, marking me the Brainliest would be awesome!
